Abstract
Abstract A method for assembling a push-up type serving container consisting of three parts, namely, a tubular container body or cylinder for a confection or other edible substance, a piston for pushing the confection upwardly to expose it at the upper open end of the cylinder, and a separate actuating rod which fits into a downwardly-opening socket at the lower side of the piston and extends downwardly through the lower end of the cylinder. The tubular container body also has axially spaced piston-stop ribs on its inner surface. The assembly is made by successively mounting the piston on the stick, and then moving the piston into the tubular container body to angle it into position between the stop ribs.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
The method of assembling a container comprising a tube with an open end having axially spaced stops on its inner surface within the end, a piston having axially spaced ends to be fitted into the tube between said stops and having a stick-receiving socket opening toward the open end of the tube, and a stick for fitting into said piston socket, which comprises: holding the stick in a fixture with its end projecting therefrom, positioning the piston relative to the fixture-supported stick to move the open end of the piston socket over the projecting end of the stick, and slipping the open end of the tube axially over the exterior of the fixture-supported stick-mounted piston until the tube engages stop means on the fixture so that the axially spaced stops of the tube engage the ends of the piston respectively to locate the piston axially in the tube.
Claim 2
Independent Claim
148 words
The method of assembling a container comprising a tube with an open end having axially spaced stops on its inner surface within the end, a piston having axially spaced ends to be fitted into the tube between said stops and having a stick-receiving socket opening toward the open end of the tube, and a stick for fitting into said piston socket, which comprises: holding the stick in a fixture with its end projecting therefrom, positioning the piston relative to the fixture-supported stick to move the open end of the piston socket over the projecting end of the stick, and slipping the open end of the tube axially over the exterior of the fixture-supported stick-mounted piston until the tube engages stop means on the fixture so that the axially spaced stops of the tube engage the ends of the piston respectively to locate the piston axially in the tube.
Claim 3
Dependent Claim
107 words
The method according to claim 1 in which: the piston of the container to be assembled has an axially-projecting skirt within its ends and the stick-receiving socket of the piston is located centrally within the skirt and projects axially in the same direction, said fixture having a stick-receiving socket in which the stick is disposed with its end projecting from said fixture socket and said fixture having a surrounding end portion over which the piston skirt is fitted simultaneously with the positioning of the piston stick-receiVing socket over the projecting end of the stick, the open end of the tube being slipped axially over the supported skirt.
Claim 4
Dependent Claim
80 words
The method of claim 2 in which: the fixture is provided with the tube-engaging stop means in the form of a stop-shoulder for limiting axial movement of the tube over the piston skirt and which is located axially inwardly of the edge of the supported skirt, and the stick-receiving socket of the fixture is enlarged at its outer end so as not to contact with the inner edge of the piston stick-receiving socket as it is moved onto the stick.
Claim 5
Dependent Claim
62 words
The method of claim 3 in which: the axially spaced stops in the tube are ribs adjacent its open end, and the open end of the tube is slipped over the skirt of the piston until the leading rib snaps over the inner end of the skirt of the piston and the following rib contacts with the outer extremity of the piston.
